Profile fitting generally involves the following steps: 1. Data Collection: Obtain experimental data using techniques such as X-ray diffraction (XRD), scanning electron microscopy (SEM), or transmission electron microscopy (TEM). 2. Model Selection: Choose an appropriate mathematical model that describes the physical properties of the nanomaterial. 3. Parameter Estimation: Use software tools to adjust the model parameters until the calculated profile matches the experimental data. 4. Validation: Verify the fit by comparing it with theoretical predictions and additional experimental data.
